74VHC174FT from TOSHIBA, in a TSSOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CLR | input | Active-low asynchronous clear; when held low the Q outputs are forced low independent of the other inputs. |
| 2 | Q1 | output | Flip-flop 1 output, takes the D1 level on the rising clock edge. |
| 3 | D1 | input | Flip-flop 1 data input, 0 to 5.5 V tolerant regardless of supply voltage. |
| 4 | D2 | input | Flip-flop 2 data input, 0 to 5.5 V tolerant regardless of supply voltage. |
| 5 | Q2 | output | Flip-flop 2 output, takes the D2 level on the rising clock edge. |
| 6 | D3 | input | Flip-flop 3 data input, 0 to 5.5 V tolerant regardless of supply voltage. |
| 7 | Q3 | output | Flip-flop 3 output, takes the D3 level on the rising clock edge. |
| 8 | GND | power_in | Ground reference (0 V). |
| 9 | CK | input | Common clock input; data is transferred to the Q outputs on the positive-going edge. |
| 10 | Q4 | output | Flip-flop 4 output, takes the D4 level on the rising clock edge. |
| 11 | D4 | input | Flip-flop 4 data input, 0 to 5.5 V tolerant regardless of supply voltage. |
| 12 | Q5 | output | Flip-flop 5 output, takes the D5 level on the rising clock edge. |
| 13 | D5 | input | Flip-flop 5 data input, 0 to 5.5 V tolerant regardless of supply voltage. |
| 14 | D6 | input | Flip-flop 6 data input, 0 to 5.5 V tolerant regardless of supply voltage. |
| 15 | Q6 | output | Flip-flop 6 output, takes the D6 level on the rising clock edge. |
| 16 | VCC | power_in | Positive supply, operating range 2.0 V to 5.5 V (absolute max -0.5 to 7.0 V). |
